Key Facts

Overview

Asteroid 2010 ER2 is an object with an orbit between Jupiter and Neptune. NASA JPL has not classified 2010 ER2 as potentially hazardous because its orbit does not bring it close to Earth.

2010 ER2 orbits the sun every 7,450 days (20.40 years), coming as close as 1.80 AU and reaching as far as 13.12 AU from the sun. Its orbit is highly elliptical.

No Close Approaches

2010 ER2's orbit is 0.98 AU from Earth's orbit at its closest point. This means that there is a very wide berth between this asteroid and Earth at all times.

Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.

Images and Observations

2010 ER2's orbit is determined by observations dating back to Feb. 22, 2010. It was last officially observed on March 6, 2010. The IAU Minor Planet Center records 23 observations used to determine its orbit.

Accessibility and Exploration

This asteroid is not considered a viable target for human exploration by the NHATS study.
